The Tungsten Connector proxy within a Tungsten Cluster is a very powerful tool, able to route traffic many different ways. The Quality Of Service (QoS) determines where the Connector proxy will send client request packets, either to the Primary for writes or to a Replica for reads. This short blog post will show you how to use the command line to control the Quality Of Service when creating a new connection to the MySQL Server database.

Part of the power of Tungsten Clustering for MySQL / MariaDB is its intelligent MySQL Proxy, known as the Tungsten Connector. Tungsten Connector has three main modes, and depending on the type of operations you are performing (such as if you need read-write splitting), we help you choose which mode is best. Hence the question, "How can I tell which Tungsten Connector mode I am using: Bridge, Proxy/Direct or Proxy/SmartScale?"

Need to do maintenance on a host? Learn how to suspend it gracefully.

Want your application to read from replicas? Here is how to choose the best r/w splitting option available in Tungsten Clustering.

How to pass arguments from an application to a database proxy, per-connection, to a Tungsten Database Proxy using connection parameters.

Thinking transparent reconnects of applications is the grail of HA? It is! But Active/Active setups make them risky.

Sometimes you really, really want to know what a MySQL client is asking of the MySQL server. As of Tungsten Clustering v7.0.0, you may now enable Connector Audit Logging, which captures data transferred between client applications and MySQL servers to a file, database or socket. This blog post will walk you through the feature and how to enable, configure and disable Tungsten Connector Audit Logging.

We are pleased to announce that Tungsten Clustering and Tungsten Replicator GA version 6.1.17 are now available. Tungsten allows enterprises running business-critical MySQL database applications to cost-effectively achieve continuous global operations with commercial-grade high availability (HA), geographically redundant disaster recovery (DR) and geographically distributed active/active.

SmartScale is a special mode of the Tungsten Connector (aka Tungsten Proxy), which allows read requests to be intelligently routed to either a replica or the primary to ensure that the data returned is not stale. This feature is available when the Connector is running in the application-layer Proxy mode. Learn more about the behavior of SmartScale in this blog.

Customers often ask where they should install their MySQL, MariaDB, or Percona MySQL database proxies for high availability clusters, and how many. What is optimal for you may not be the right configuration for everyone. However there are some best practices we’ll discuss in this basic blog about deploying MySQL database proxies.

How the Continuent Proxy selects database cluster nodes for executing read operations.

In this short blog post, we examine the impact that setting the Tungsten cluster policy to Maintenance has on the cluster behavior, and specifically the impact on the Tungsten Connector.
